Chapter 2.4 Operations with Functions (Perform operations with functions to write new functions).Operations with functions are listed in the blue section of the top of the page 112.
Read examples 1 and 2 on page 112. Then try to reproduce these problems on your own. If you make a mistake, read the the textbook solution again. Again, try to solve the examples 1 and on your own (without looking in the textbook). If you still have problems, you have to review the distributive properties (example 2 p.88) and properties of exponents (example 2 p.96). Practice p.115 #11-29 odd. Homework assigned on 10.19. for 10.20.2009
p.115 #14,16,20-34 even. To solve these problems, study examples 1 and 2 on page 112 and look for the advice above. October 20, 2009

Chapter 2.5 Inverses of Functions. Definition of Inverse of a Relation (blue section on the bottom of the page 118). Study examples #2 and #3 on page 119. Practice p.122 #11-25 odd, p.122 #29-39 odd. Homework assigned on 10.22 for 10.27.2009
p.122 #18-26 even and #30-38 even
Study example #2 on p.119 before you start working on #18-26.
In 18-26 switch x and y to find Inverse of a given relation. The relation is a function if all x in a given relation are different. You have to make a decision for both an original relation and its inverse separately.
Carefully study example #3 on page 119 before you start working on #30-38.
In these problems use y instead of f(x), g(x), and h(x). Then substitute x for y and y for x.
Finally, solve for y. Hints for #34-38 are in the link below.

You can only use notebook on this test.
Please, bring small a ruler. You do not need textbook on the day of the test, on Monday October 19th.
Additional time to finish the test will be given only to the students who came on time on the day of the test.
The students who get 90% on this test will have a privilege to take Chapter 3 test home next time provided they have a good behavior effort, come on time to every class, carry all necessary materials to the class, do their homework and most of the work in class. October 19, 2009. Chapter 2 Test.
